Upon starting 'Phoenix', your primary objective is to infiltrate the heavily guarded U-boat facility. Follow your squadmates, particularly Lucas Riggs, who will often provide cues for synchronized takedowns. Stick to cover and use your suppressed Sten to eliminate isolated enemies. When you encounter groups, look for opportunities to perform a synchronized takedown with your team – usually indicated by a prompt. Avoid direct confrontations initially, as the enemy numbers can quickly overwhelm you. There's a section where you'll need to disable searchlights; shoot them out from a distance to maintain stealth. As you progress deeper, you'll encounter more patrols. Utilize environmental cover like crates and machinery to break line of sight and flank enemies. The path is fairly linear, but always be aware of potential flanking routes for the enemy.
